⚫
If "free stop" is selected, the frequency inverter displays Err** and directly stops.
⚫
If "Stop according to the stop mode" is selected, the frequency inverter displays A** and stops according to the
stop mode. After stop, the frequency inverter displays Err**.
⚫
If "Continue to run" is selected, the frequency inverter continues to run and displays A**. The running frequency
is set in bb-37.

If a fault occurs during the running of the frequency inverter and the handling of fault is set to "continue to run", the
frequency inverter displays A** and continues to run at the frequency set in bb-37.
The setting of bb-38 is a percentage relative to the maximum frequency.

First fault type
0~99
bC-01
Second fault type
bC-02
Third fault type (latest)
It is used to record the types of the most recent three faults of the frequency inverter. 0 indicates no fault. For possible
causes and solution of each fault, refer to Chapter 7.
bC-03
Frequency of latest fault
Default
0
Description
It displays the frequency when the latest fault occurs.
bC-04
Current of latest fault
Default
0
Description
It displays the current when the latest fault occurs.
bC-05
DC Bus voltage of latest fault
Default
0
Description
It displays the DC bus voltage when the latest fault occurs.
